Connecting the PDU
2-1
Connect Input Plug Adapters (Optional -
Model PDUMH20AT Only). The PDU
includes two adapters that convert one or both
of the L5-20P input plugs to 5-20P input plugs.
Connecting the adapters is optional. The PDU
will function normally without connecting the
adapters.
2-2
Connect Secondary Input Cord to PDU.
Although the PDU will operate without
connecting the Secondary input cord, the
Secondary input is required for the PDU's
Automatic Transfer Switch function.
2-3
Connect PDU Input Plugs. Connect the
Primary input plug to a preferred source of
A
grounded 120V AC power, such as a
™
SmartOnline UPS System. The UPS system
must not share a circuit with a heavy electrical
load (such as an air conditioner or refrigerator).
Under normal operating conditions, the PDU
will distribute AC power from the Primary
input source. Connect the Secondary input plug
to an alternative source of grounded 120V
B
AC power, such as a redundant SmartOnline
UPS System. The UPS system must not share a
circuit with a heavy electrical load (such as an
air conditioner or refrigerator). Do not plug the
Secondary input into the same power source as
the Primary input. The PDU will distribute AC
power from the Secondary input only if the
Primary input becomes unavailable. See the
Configuration and Operation section for more
information.
Note: Immediately after the PDU is connected to live AC
power, you may notice a series of soft clicking sounds emitted
by electrical relays within the PDU. The relays may also click
occasionally during the operation of the PDU. This is normal.
